Yesterday, MTV dished out the Female Top Rookies for 2009, now it’s the guys’ turn.

Frankie Jonas, Jackson Rathbone, Mitchel Musso and Lucas Grabeel all are ready to take center stage in 2009.

Lucas, 23, shares with the music channel, “You better watch out because I now have new acquired kung-fu skills and mixed with my jazz squares, it’s pretty lethal. I’ve just started working on a new film called Legend of the Dancing Ninja. I combine some dancing skills with a lot of fighting, kung-fu skills.”

Frankie Jonas, aka The Bonus Jonas, is arguably the youngest and coolest Jonas brother. The 8-year-old was recently interviewed by famed YouTubers Katie and Karleigh in a conference room.

Frankie opened up about himself — not his famous, older brothers! — and talked about his ambition to start a band of his own, his favorite things and the Nintendo Wii.

He shared, “Me and my friends, we call it The Hollywood Shake-Up. So far, there’s only me and my friend and when we recorded, we just did auto-mix. We were like, we need to find some people.”

WHAT DO YOU THINK of Frankie starting his own band?

The Jonas Brothers hooked up with Jimmy Kimmel last night to talk about their lil bro Frankie (“The Bonus Jonas”) being the most popular, their brand-new book, “Burning Up: On Tour with the Jonas Brothers,” and even took questions from fans outside the ABC studios.

We learned a lot of new things about Nick, Joe and Kevin too! Did you know that Joe, 19, is a certified babysitter. “In New Jersey. There was this girl I liked and yeah…” he tells Jimmy.

Kevin, 21, quickly added, “This was around the time Frankie was born and she said, ‘Hey, this is a good idea.’” Watch the JoBros‘ appearance on Kimmel below!
